Exclusive OCL400 Series Features
1. Exclusive ServoDrive *system provides variable speed and rotational
torque during computerized compensation and rotor machining.
4
2. Pro-Comp ® computerized compensation* adjusts for lateral runout
with a push of a button and a simple single-point adjustment.
3. ACT (Anti-Chatter Technology)* oscillates spindle speed to
eliminate chatter and provide a smooth surface finish.
4. Large 1.5-hp motors easily service 4WD vehicles (OCL410) or
medium-duty front and rear truck rotors (OCL430MD).

5. Long-life micro-round cutting inserts withstand “crashes” and
heavy cuts, removing up to .040 inches per side in one pass.
6. Large, rigid tool holders service rotors up to 15.75 inches in
diameter and 2.75 inches in thickness (OCL400) and 17.5
inches in diameter and 3.5 inches in thickness (OCL430MD). †

7. Offset cutting arm is freely adjustable when lathe is rotated
180° for servicing opposite side of vehicle. No need for
unbolting, removing and reinstalling cutter head.
8. Rugged I-beam construction is more rigid than “dovetail” slide
designs. Slide location outside the vehicle fender is isolated
from brake chips and dirt build-up.
9. Pivoting control module, exclusive twin-cutter design and easily
accessible adjustment controls allow adjustment in same
manner right side up or upside down.

0CL400 Series Feature Comparison
OCL410
OCL430MD
Large cutting arm and rigid tool holders
handle rotors up to 15.75 inches in
diameter and 2.75 inches in thickness.
Heavy-duty cutting arm and tool holders
handle rotors up to 17.5 inches in diameter
and up to 3.5 inches in thickness.
Rigid I-beam slide tool feed design.
A more robust I-beam slide and main
housing support the precision machining
of medium-duty, commercial-grade rotors.
Large 1.5-hp motor for easy
service of 4WD vehicles.
Heavy-duty 1.5-hp, 230VAC, 50-60 Hz,
9-Amp motor handles medium-duty
front and rear truck rotors.
OCL430MD Rotor Lathe for Medium-Duty
Trucks and Commercial Vehicles
The OCL430MD is the ideal solution for shops that
service medium-duty trucks and commercial vehicles
exclusively or as a significant part of their business.
It offers all of the speed and productivity features of the
Hunter OCL400 brake lathe, but adds heavy-duty design
features, components, rotor size capacity and power.
The OCL430MD trolley provides an extended lowto-high
working range required for servicing
vehicles when a lift rack is not available or practical.
A full selection of adaptors and accessories to
match medium-duty, commercial-grade vehicle hub
and rotor OE specifications is available from Hunter.

Increase Production, Reduce Comebacks With
Innovative OCL400 Series Lathe Technology
ServoDrive Variable Drive System
Speeds Brake Service!
The patented ServoDrive variable drive system enables technicians to service rotors
in half the time of other on-car lathes by providing variable speed and rotational
torque during compensation and machining. Technicians can resurface rotors at the
fastest possible speed and change speeds on the fly. The ServoDrive system allows
service of rear locking differentials popular on light trucks and SUVs without the need
to remove or disengage drive line components.
Intermittant Cutting Pattern Produces

Intermittent
Cutting Pattern

Continuous
Cutting Pattern
Model Shown
OCL410-LT-PRO
Exclusive Hunter intermittent tool feed produces
a non-directional cutting pattern of interrupted
arcs, which eliminates radial “push-out” effect
that continuous feed units present. Surface
finish quality remains consistent regardless of
changes to cutting speed during machining.

Exclusive Anti-Chatter Technology
Provides Superior Finish
Anti-Chatter
Technology
New Anti-Chatter Technology (ACT) feature oscillates the machining speed of
the lathe and eliminates the buildup of vibration (chatter) that can occur when
machining at a fixed speed. ACT provides a smoother finish that prevents pedal
pulsation - the number one cause of brake service customer "comebacks".
Fixed-Speed Machining
Fixed-speed lathes can “tune in” to the natural frequency of a rotor during
machining, causing vibration (chatter) and a poor surface finish.
Variable Speed Machining
With the push of a button, ACT begins oscillating the spindle speed of the
lathe, eliminating chatter and resulting in a smooth surface finish.

Pro-Comp Computerized Compensation Speeds
OCL400 Series Operations
With a push of a button and a simple single-point adjustment, the OCL410 and
OCL430MD quickly compensate for lateral runout. Compensation is greatly simplified,
no longer requiring time-consuming dial indicators or special tools. This ensures your
brake service technician is machining the rotor within OEM specifications.
Service Each Rotor in Less Than 9 Minutes!
Step 1: Attach adaptor and
lathe...
Step 2: Press button for
computerized compensation
and make a simple singlepoint
adjustment...
Step 3: Adjust cut depth and
machine rotor with on-the-fly
optimum speed.
Service Complete!
Other Compensation Methods and Models
Manual Single-Point Compensation Model
OCL360S
Compensation of the hub, adaptor and lathe is achieved
with a single-point adjustment. The compensation
process adjusting time is simplified and reduced.
Manual Three-Point Compensation Model
OCL360
Manual three-point runout compensation is
accomplished at the adaptor. The lathe is then
attached and the rotor machined.
The ServoDrive TM System, Pro-Comp ® Computerized Compensation and ACT Anti-Chatter
Technology are not available on OCL360 and OCL360S models.
